Description
Descrizione di invenzione industriale Description of industrial invention
L'invenzione concerne un'unità di confezionamento per prodotti fluidi. Lo stato della tecnica comprende delle unità di confezionamento ottenute da una coppia di gusci uniti lungo il contorno e definenti tra essi una cavità contenente il prodotto. Per la fuoriuscita del prodotto, tali contenitori sono trasversalmente dotati di un'incisione a frattura prestabilita in corrispondenza della quale il contenitore si può facilmente aprire per l'azione di una modesta forza che tenda a separare una parte terminale del contenitore dal corpo dello stesso. Dal momento che la linea di frattura prestabilita è prevista in corrispondenza di un'appendice tubolare della cavità interna del contenitore, ciò provoca l'apertura di un condotto attraverso il quale il prodotto può essere fatto uscire dalla cavità, esercitando uno schiacciamento delle pareti del contenitore. Peraltro, in tali contenitori, la linea di frattura prestabilita è disposta trasversalmente rispetto all'appendice tubolare e, quando il contenitore è aperto, tra il bordo risultante dalla fattura e i bordi laterali del contenitore vengono definiti spigoli vivi che possono risultare taglienti, o provocare escoriazioni, o graffi. The invention relates to a packaging unit for fluid products. The state of the art comprises packaging units obtained from a pair of shells joined along the contour and defining between them a cavity containing the product. For the product to come out, these containers are transversely provided with a predetermined fracture incision at which the container can be easily opened by the action of a modest force which tends to separate an end part of the container from the body of the same. Since the predetermined fracture line is provided in correspondence with a tubular appendage of the internal cavity of the container, this causes the opening of a duct through which the product can be made to exit the cavity, exerting a squeezing of the walls of the container. . Moreover, in these containers, the predetermined fracture line is arranged transversely with respect to the tubular appendage and, when the container is open, sharp edges are defined between the edge resulting from the invoice and the lateral edges of the container, which can be sharp or cause abrasions. , or scratches.
Cosi, tali contenitori, che, per il costo modesto, vengono ad esempio correntemente impiegati per il confezionamento di campioni omaggio monodose a perdere, non possono trovare applicazione nei settori farmaceutico ed alimentare, in considerazione del loro potenziale di offesa al consumatore. Thus, these containers, which, due to their modest cost, are currently used for example for the packaging of disposable single-dose complimentary samples, cannot find application in the pharmaceutical and food sectors, in consideration of their potential for offense to the consumer.
Tale stato anteriore della tecnica è suscettibile di ulteriori perfezionamenti con riguardo alla possibilità di eliminare gli inconvenienti sopra indicati. This prior state of the art is susceptible of further improvements with regard to the possibility of eliminating the aforementioned drawbacks.
Scopo dell'invenzione è di diminuire considerevolmente la pericolosità dei contenitori sopra descritti, in particolare di evitare che possano ferire o danneggiare il consumatore quando aperti. The object of the invention is to considerably reduce the danger of the containers described above, in particular to prevent them from injuring or damaging the consumer when opened.
L'invenzione risolve il problema tecnico suddetto adottando un'unità di confezionamento, comprendente due elementi contrapposti di materiale in foglio, almeno uno dei quali concavo, uniti lungo il contorno tramite una saldatura e definenti una cavità contenente un prodotto fluido, la cavità essendo attraversata da una incisione definente una linea di frattura prestabilita per detti elementi prolungantesi fino ad intersecare zone contrapposte di detta saldatura, caratterizzata da ciò, che detta linea di frattura presenta un profilo convesso avente concavità rivolta verso detta cavità e sostanzialmente raccordantesi con le parti di detta saldatura che rimangono associate alla unità di confezionamento dopo l'apertura. The invention solves the aforementioned technical problem by adopting a packaging unit, comprising two opposing elements of sheet material, at least one of which concave, joined along the contour by a weld and defining a cavity containing a fluid product, the cavity being crossed by an incision defining a predetermined fracture line for said elements extending until it intersects opposite regions of said weld, characterized by this, that said fracture line has a convex profile having a concavity facing towards said cavity and substantially connecting with the parts of said weld which remain associated with the packaging unit after opening.
Pertanto, viene evitata la formazione di spigoli taglienti, o abradenti nel contenitore aperto, così da rendere possibile l'adozione dell'unità di confezionamento secondo l'invenzione per medicinali, ad esempio per impiego oftalmico, od orofaringeo, così come per prodotti alimentari, da assumere direttamente dall'unità di confezionamento senza rischi per il consumatore. Therefore, the formation of sharp or abrading edges in the open container is avoided, so as to make it possible to adopt the packaging unit according to the invention for medicines, for example for ophthalmic or oropharyngeal use, as well as for food products, to be taken directly from the packaging unit without risk for the consumer.
Alcuni modi di attuare l'invenzione sono illustrati, a puro titolo esemplificativo, nelle tre tavole di disegno allegate, in cui: Figura 1 è una vista frontale di un'unità di confezionamento; Figura 2 è una vista da destra di Figura 1; Figura 3 è una vista dall'alto di Figura 1; Figura 4 è una vista frontale come quella di Figura 1, ma relativa ad una versione di contenitore definito da gusci simmetrici contrapposti e bordi laterali dotati di recessi per facilitare l'apertura; Figura 5 è una vista da destra di Figura 4; Figura 6 è una vista come quella di Figura 5, ma relativa ad un contenitore stand-up; Figura 7 è una vista come quella di Figura 6, ma relativa ad un contenitore stand-up con fondo piatto. Some ways of carrying out the invention are illustrated, purely by way of example, in the three attached drawing tables, in which: Figure 1 is a front view of a packaging unit; Figure 2 is a right view of Figure 1; Figure 3 is a top view of Figure 1; Figure 4 is a front view like that of Figure 1, but relating to a version of the container defined by opposing symmetrical shells and side edges provided with recesses to facilitate opening; Figure 5 is a right view of Figure 4; Figure 6 is a view like that of Figure 5, but relating to a stand-up container; Figure 7 is a view like that of Figure 6, but relating to a stand-up container with a flat bottom.
Come evidenziato nelle Figure 1 e 2, un contenitore 1 è formato da un primo foglio 2 sostanzialmente piano e da un secondo foglio 3 concavo, uniti lungo una saldatura 4 periferica definente il contorno del contenitore, i fogli essendo di materiale termoformabile per soffiatura. La cavità definita dal secondo foglio 3 è resa comunicante con un recesso tubolare 6, circondato su tre lati dalla saldatura 4, tramite un condotto 5 sfociante in detto recesso in corrispondenza di un suo lato aperto ed un elemento ad imbuto 7 fungente da elemento di raccordo tra la cavità ed il condotto 5. As shown in Figures 1 and 2, a container 1 is formed by a first substantially flat sheet 2 and by a second concave sheet 3, joined along a peripheral seal 4 defining the contour of the container, the sheets being of thermoformable material by blowing. The cavity defined by the second sheet 3 is made communicating with a tubular recess 6, surrounded on three sides by the weld 4, through a duct 5 leading into said recess at one of its open sides and a funnel-shaped element 7 acting as a connecting element between the cavity and the duct 5.
Le dimensioni trasversali del recesso 6 sono sensibilmente minori delle dimensioni trasversali del condotto 5 e queste ultime sono sensibilmente minori di quelle della cavità. Conseguentemente, la saldatura 4 presenta larghezza crescente procedendo dalla cavità al recesso 6. The transverse dimensions of the recess 6 are significantly smaller than the transverse dimensions of the duct 5 and the latter are significantly smaller than those of the cavity. Consequently, the weld 4 has an increasing width proceeding from the cavity to the recess 6.
Come evidenziato nella Figura 3, il recesso 6 può avere una forma di sezione trasversale lenticolare, fungente da valvola atta ad ostacolare la fuoriuscita accidentale del prodotto e consentirne la fuoriuscita solo quando le pareti della cavità siano assoggettate ad un lieve schiacciamento. As shown in Figure 3, the recess 6 can have a lenticular cross-sectional shape, acting as a valve capable of hindering the accidental release of the product and allowing it to escape only when the cavity walls are subjected to a slight crushing.
Il recesso 6 è trasversalmente attraversato da una linea 8 di frattura prestabilita prolungantesi lateralmente per tutta la larghezza di corrispondenti parti di saldatura 4 contrapposte da essa interessate ed avente un profilo arcuato convesso sostanzialmente raccordato con i bordi laterali esterni 9 del contenitore 1. The recess 6 is transversely crossed by a predetermined fracture line 8 extending laterally for the entire width of the corresponding opposing welding parts 4 affected by it and having a convex arched profile substantially joined with the external lateral edges 9 of the container 1.
In questo modo, quando il consumatore desidera ingerire un prodotto, o assumere un farmaco confezionato nel contenitore, può semplicemente strappare la parte 10 amovibile della saldatura 4 situata dalla parte della linea di frattura 8 opposta rispetto alla cavità, ricavando così un contenitore aperto in corrispondenza di detto recesso 6 e privo di spigoli taglienti o abradenti. In this way, when the consumer wishes to ingest a product, or to take a drug packaged in the container, he can simply tear off the removable part 10 of the seal 4 located on the part of the fracture line 8 opposite the cavity, thus obtaining an open container in correspondence of said recess 6 and devoid of sharp or abrading edges.
Come illustrato in Figura 4, la linea di frattura prestabilita 8 può essere combinata con rispettivi tratti rientranti 11 dei bordi 9, in modo da definire tutt'al più angoli A, B molto ottusi tra le zone d'estremità della linea 8 e le parti dei bordi 9 giacenti dal lato della cavità. Mentre con B si è inicato l'angolo definito tra un bordo 9 ed un tratto rettilineo del recesso 11 , con A si intende l'angolo definito tra la tangente T ad un'estremità della linea di frattura 8 ed un tratto rettilineo di detto recesso 11. L'ampiezza degli angoli A, B è sufficiente a garantire che il contenitore aperto non possa offendere il consumatore, anche quando venga impiegato per distribuire collirio. As illustrated in Figure 4, the predetermined fracture line 8 can be combined with respective recessed portions 11 of the edges 9, so as to define at most very obtuse angles A, B between the end zones of the line 8 and the parts of the edges 9 lying on the side of the cavity. While with B the angle defined between an edge 9 and a rectilinear portion of the recess 11 is indicated, with A we mean the angle defined between the tangent T at one end of the fracture line 8 and a rectilinear portion of said recess 11. The width of the corners A, B is sufficient to ensure that the opened container cannot offend the consumer, even when used to distribute eye drops.
Come si può vedere dalla Figura 5, il contenitore 1 può essere definito da una coppia di gusci corrispondenti ciascuno ad un secondo foglio 3, contrapposti ed uniti lungo la saldatura 4: in tal modo vengono ottenuti contenitori 1 aventi una maggiore capacità. As can be seen from Figure 5, the container 1 can be defined by a pair of shells each corresponding to a second sheet 3, opposed and joined along the seal 4: in this way containers 1 having a greater capacity are obtained.
Inoltre, come evidenziato nelle Figure 6, 7, il contenitore può essere del tipo stand-by, con fondo 12 concavo, oppure con fondo 13 piatto. Furthermore, as shown in Figures 6, 7, the container can be of the stand-by type, with a concave bottom 12, or with a flat bottom 13.
Il contenitore 1 può essere ad esempio ottenuto con i procedimenti di termoformatura ad iniezione noti da WO94/08852. The container 1 can be obtained for example with the injection thermoforming processes known from WO94 / 08852.
Inoltre, la linea di frattura prestabilita 8 può essere ricavata tramite un normale punzone per incisione, con profilo di tagliente sagomato sostanzialmente secondo il profilo della linea stessa. La forma esterna della saldatura 4, compresi gli eventuali recessi 11, può essere realizzata secondo qualsiasi profilo per mezzo di idonei punzoni di tranciatura. Furthermore, the predetermined fracture line 8 can be obtained by means of a normal engraving punch, with a cutting edge profile substantially shaped according to the profile of the line itself. The external shape of the weld 4, including any recesses 11, can be made according to any profile by means of suitable blanking punches.
Nell'attuazione pratica, i materiali, le dimensioni, i particolari esecutivi, potranno essere diversi da quelli indicati, ma ad essi tecnicamente equivalenti, senza per questo uscire dal dominio giuridico della presente invenzione. In the practical implementation, the materials, the dimensions, the executive details, may be different from those indicated, but technically equivalent to them, without thereby departing from the legal domain of the present invention.
